MACHINE FOR CUTTING SHINGLES FROM STEAMED, BOILED, 0R OTHER TIMBER.

Specification of Letters Patent No. 1,319', dated September 10, 1839.

To all 'whom t may concern;

Be it known that we, DANIEL O. McMin- LAN and JOHN B. KNoLL, of Persia,in the county of Oattaraugus, THOMAS S. HENRY, of Collins, in the countyof Erie, and MATHEW KNOLL, of Tully, in the county of Onondaga, all inthe State of New York, have invented certain Improvements in Machinesfor Cutting Shingles from Steamed, Boiled, or other Timber, by means ofwhich improvements the timber to be cut is vibrated so as alternately toproduce a butt and tip at either end and is fed up to the knife in amore advantageous manner than has hitherto been effected; aiidwe dohereby declare that the following is a full and exact descriptiont-hereof.

The knife by which the shingles are to be cut extends across a.vibrating frame, or gate, which works up and down between fender posts,or cheek pieces, in a vertical frame. The bolt, or timber, from whichthe shingles are to be cut, is placed upon a head block resting upon atable in front of the machine, said bolt, or timber, being held firmlyon the head block, by means of suitable dogs, or other devices. Avibratory, and also a progressive, motion is given to the head block bywhich the slope and thickness of the shingle are regulated.

Figure l is a perspective representation of the machine, A, A, A, beingthe stationary frame Within which t-he gate B, carrying the knife O,works up and down.

D, is a flat table fixed to the frame A, A of the machine, and E, thehead block upon which the bolt, or timber, is to be held, which may beeifected by means of the dogs N, N, operated by the lever O, as in someother machines; ci, a, is a segment of a circle which may have notcheson its face to receive the handle O, and vhold it in any requiredposition.

Q, Q, are strips, or flat bars, of iron serving as ways upon which thehead block may vibrate, and slide. F, is a. lever by which the frame B,is to be made to vibrate, and this may be operated upon by water,animal, or other, power, in ways perfectly well known to machinists. Theconnection of the lever F, with the vibrating frame B, is shown at Z),Fig. 2, which is a front view of that part of the frame.

M, M, W, lV, are pieces of timber constituting the back frame forsupporting the vibrating apparatus and its appendages.

H, is a fiat vibrating bar, or lever, which serves to vibrate andadvance the timber upon the head block; at its rear end, itrests table,and F, the head block. The lever H,

bends up at its fore end H', and is fastened to the head block E. Thislever vibrates `upon a pin 0, attached to a bar el, Figs. 3

and 4, which crosses from one fender post to the other immediately underthe knife, and below the table D, the pin c, passing into the slot e,which allows the lever H, to inove back and fort-h, and also to vibrateupon the pin.

P, P, are two standards which rise from the cross timber WV, Figs. l,and 4c, and support a revolving cylinder J, Figs. 1, 2, 3, and 4, bywhich the lever H, is made to vibrate and advance. Upon one end of thecylinder, there are four projecting pins f, f, f, f, and a part of thecylinder is cut away between them to allow of the free action of a pawl,or hand, K, which is to act upon them and Cause the cylinder at eachcontact to make one-fourth of a revolution. The hand K, is attached to,and works upon, a joint on the lower rail of the knife frame, the jointallowing of its free descent over the pin upon which it is next to act.The lever H, is made to vibrate by means of four beveled pins g, g,rising from the cylinder J, and coming alternately into contact withopposite sides of the lever H, the edges of which are also beveled, sothat it is wedged, or pushed over, from side to side, to the properdistance to give the desired slope to the shingle. To cause the headblock to advance as well as to vibrate, the rear end of the lever H, hasangular teeth formed upon each of its sides, as at 7L, it; and there aretwo angular teeth z', z', which rise from the timber lW, which teethalternately engage with those of the lever H, as it is wedged over fromside to side, these draw it forward the thickness of a shingle.

V/hen the butt, or timber, has advanced so as to bring the head blockclose to the knife, the lever H, is thrown out of gear by the followingmeans; m, in the respective figures, is a screw nut, litting on to ascrew on the upper end of a bolt n, which is capable of sliding up anddown in the back part of the tiinber W, and when the bolt is held down,the

lever H, is in gear With the teeth i, z', and with the pins g, g, on thecylinder J; but when the bolt n, is raised, the lever H, is lifted outof gear. Fig. 5, is a back view of a part of the machine showing thisbolt and its appendages. In the bolt n, there is a recess into which theend of a spring, 0, is received and which when in place holds the boltn, down; p, is a spring which bears upon the bottom of this bolt, andforces it up when not held down by the spring 0. .To disengage this,there is a lever g which passes up immediately within the spring 0,' andupon the vibrating lever H, there is a disengaging piece L, which as itadvances comes into contact with the upper end of the lever g, andthrows the machine out of gear. The screw part of the bolt n, passesthrough a slot r, r, in the lever H, to allow of the advancing motion ofthe said lever.

Instead of forming the angular teeth on the outer edges of the lever H,said lever may be divided into two parallel parts, by a slot, oropening, along it, and the teeth may be formed on the two interioredges.

Having thus fully described the construction of our machine and shownthe manner in which the same operates, we wish it to be distinctlyunderstood that we do not claim the manner of cutting shingles by meansof a knife attached to a vibrating frame, or

gate, nor do we claim the manner of securing the bolt, or timber, uponthe head blocl; but we limit our claim to the manner of vibrating, andof feeding the stuff to the knife, and of disengaging the vibratinglever; that is to say, we claiml. rIhe manner in which we cause thevibrating lever to vibrate and advance, by the combined operation of therevolving cylinder, furnishes with the beveled pins g, g, acting uponsaid lever, the cylinder being made to revolve in the manner set forth,and the lever, and, consequently, the head block, being made to advanceby the combined action thereon, of the teeth 7L, L, and z', as setforth.

2. We also claim the particular arrangement of the parts for throwingthe vibrating lever out of gear, by the combined operation of thedisengaging piece L, the bolt fn., the lever g, and the spring p,constructed and arranged, substantially, in the manner described.
